摘　　要：回顾性分析8例经病理证实的肺部原发肉瘤样癌的多层CT表现,并复习文献.右肺上叶5例、下叶2例,左肺上叶1例;1例因肿块巨大未分型,其余7例均为周围型;4例见假包膜,1例见粗大钙化,肺门、纵隔淋巴结转移2例,空洞1例,1例伴广泛小叶间隔增厚及磨玻璃密度影,2例肿块有深分叶及毛刺;1例仅行CT平扫,余7例行平扫及增强CT检查,其中6例呈进行性强化,5例强化不均,肿块呈厚薄不均的环形强化,4例可见“浮冰样”表现.肺部原发肉瘤样癌以上叶胸膜下区常见;“浮冰样”表现对肉瘤样癌有一定诊断价值.Retrospective analysis of multi-slice computed tomography （MSCT） manifestations were conducted for 8 cases of pathologically confirmed primary pulmonary sarcomatoid carcinoma.And the relevant literature was also reviewed.The lesion sites were right upper lobe （n =5）,lower lobe （n =2） and left upper lobe （n =1）.One case was difficult to distinguish because of its huge mass and the remainder was all peripheral.With pseudocapsule （n =4）,coarse calcification （n =1）,hilar ＆ mediastinal node metastasis （n =2） and cavity （n =1）.The manifestations included extensive lung alveolar septal thickening ＆ ground glass （n =1） and massive deep leaf ＆ glitches （n =2）.The scans were non-enhanced alone （n =1） and non-enhanced ＆ enhanced （n =7）.Six cases had shaped enhancement while another 5 uneven thickness of annular enhancement.And 4 cases had ＂floating-ice＂ change.Primary pulmonary sarcomatoid carcinoma is common in subpleural lung lobe.And the ＂floating-ice＂ sign is valuable in the diagnosis of sarcomatoid carcinoma.
